I wish they added the same thing JS has, where this "string literal prefix thingy" can be user-defined.

html`<p>${value}</p>` will actually run the function html(template). This means you can use this to "mark" a function in a way that can be detected by static analysis. Many editors will, for example, syntax highlight and lint any HTML marked this way, same with SQL, GraphQL and probably some others too.

The PEP was initially proposed this way. But due to various reasons, making it an open namespace was considered to overcomplicate the language (read: understanding coffee when reading it). Alternatively, there doesn't really seem to be much loss of ability with t-strings. Libraries can require a template as it's accepted type, instead of having to invent their own custom type and named template.
